What is Viagra?

 Viagra is a brand-name drug approved for the treatment of erectile dysfunction. With ED you will not be able to maintain or maintain an erection. Viagra is approved for use in men 18 years of age and older.

Viagra contains the drug sildenafil. It belongs to a class of medicines called phosphodiesterase type 5 (PDE5) inhibitors. (A class of drugs is a group of medications that work similarly.) Viagra works by increasing blood flow to the penis, helping you to maintain and maintain an erection. But this drug works only if you are sexually aroused. So its preferable to 비아그라 

Viagra comes in the form of tablets that are taken orally. In most cases, it should be taken about an hour before sexual activity, but it can be taken from 30 minutes to 4 hours. Viagra is available in three strengths: 25 mg, 50 mg and 100 mg.

Does Viagra work to treat ED?

Yes, that's right. In several clinical trials, Viagra has been effective in treating ED. In these studies, men who used the drug had improved erection ability and maintained erections, allowing for successful sex.

During the studies, an erection improved from 43% to 83% of men. (These rates varied depending on the cause of their ed and the dose of Viagra.) By comparison, improved erections occurred in 10% to 24% of men who received placebo (not an active drug).
